    Industrial Demonstrators for Sustainable Cities

    The Vivapolis network aims to federate French public and private stakeholders involved in conceiving, building and operating sustainable cities, in France or abroad, in order to improve synergy and help them be, individually and collectively, more efficient in their action.

    These sheets have been produced by the Vivapolis network members who attented different work groups to promote examples of innovative solutions for sustainables cities.

  • /// A MECHANISM FOR PUBLIC-PRIVATE GROUPINGS

    The call for Industrial Demonstrators for the Sustainable City projects (Démonstrateurs industriels pour la ville dura- ble - DIVD) is aimed at companies of various sizes and busi- ness lines: SMEs, start-ups, large groups in the construction industry, digital technology, transport and urban service sectors, as well as universities, public establishments, etc. These companies and the regional authorities support- ing them form public-private consortiums, which locally deploy technical, organizational and governance inno- vations at all the stages of the urban design.

    A dedicated interministerial team

    Assistance from the State is provided in project mode by a dedicated interministerial team, in liaison with the Minis- tries, Directorates and regulatory bodies concerned.

    For each DIVD, we appoint: • a national referent for the Urban Planning Construction

    Architecture Plan; • A local correspondent, within the decentralized depart-

    ments in charge of development.

    Assistance to remove the technical, legal and financial barriers to innovation

    In the future, the industrial demonstrators will be show- casing French expertise internationally.

    For this reason, the State assists them to remove the barri- ers to realizing their projects with: • technical and legal support and the implementation of

    the derogation mechanisms provided for in the law; • financial support for the engineering; • the coordination of an exchange network; • the national and international promotion of the projects.

    We do not want to deregulate the procedures but we realize that in land planning and development it is sometimes necessary to knock down a

    few barriers. The support from the State […] facil- itates dialogue, and that should be emphasized.

    Bruno Tirmant VNF, at the DIVD club of 13 January 2017

    INDUSTRIAL DEMONSTRATORS FOR SUSTAINABLE CITIES A SPECIFIC SUPPORT FROM THE STATE

  • /// A COLLECTIVE TAILOR-MADE APPROACH

    The State in touch with the DIVD Club

    Through this approach, the State and the companies adapt their mode of functioning to guarantee the agility that is necessary for the innovation process.

    To co-build and guide the approach, the demonstrators’ ‘club’ is invited twice a year by the State.

    An innovative method: the example of the ‘barrier group’ (French: “groupe verrou”)

    The ‘barrier group’ brings together the industrial demon- strators for the sustainable city and supportive experts, in order to: • identify the technical and legal barriers to the realizing

    the projects; • act out the State’s commitment to contribute to remov-

    ing them; • share the solutions and good practices.

    A COMMITTEE OF PARTNERS

  • In Carquefou, 600 housing units with a passive objective have been built. The ZAC (joint development zone) of La Fleuriaye in Carquefou is an environmental equation com- bining biodiversity, passive construction, and renewable energy. This project has successively been labelled Indus- trial Demonstrator for sustainable cities in March 2016, then was certified SMILE (Smart Ideas to link Energy) in February 2018 and was finally awarded the Grand Prix of the Green solutions Awards, in the district category.

    INNOVATIONS Energy-neutral district: production greater than or

    equal to consumption, innovative legal set-up for photo- voltaic technology, development of communication-ca- pable transformers, technical and economic optimization on all the processes. Development of Smart Grids in new and existing buildings for optimization purposes but also for educational and societal purposes (Display screen).

    Passive construction enables the 3 aspects of sustain- able development mentioned above to be combined by proposing to more than 1,000 inhabitants: • Lower energy costs • Cleaner air to breathe • A reduction in overheating in the summer

    The flats will be equipped with a new generation of electric meters allowing tenants to monitor their con- sumption. According to current estimates, for a 60 m² flat, the average annual heating bill would be around €100.

    All the south-facing roofs will be equipped with photo- voltaic panels, and at least 80% of the district’s electric- ity consumption will come from renewable energy. This enables the operation to be eligible for the “Bâtiment Passif Plus ou Premium” (Passive Building Plus or Pre- mium) labeling, by being virtually self-sufficient in renew- able energy. The objective is to reach a 100% coverage of the total consumption in primary energy for all uses of the buildings.

    OBJECTIVES

    620 housing units (320 1st phase and 300 2nd phase) as unrestricted housing, afford- able housing, assisted rental, unrestricted lots, 5,000 m2 of tertiary buildings, an equestrian center, a Medical Educational Institute. The aim is to create:

    • a real living environment combining cultural facilities (theater, FRAC (regional fund for contemporary art), music school), tertiary activities: 120 companies, 1,500 employees, 1,600 housing units in the long term, leisure facilities (bowling, equestrian stopover) and proximity of shops;

    • socially mixed housing, with 30% of rental flats for social housing, 25% of affordable housing and 45% of unrestricted housing in Fleuriaye Ouest;

    • functionally mixed with a diversity of service and tertiary activities, public and private facili- ties all within a 100 ha basin that is pleasant to live in.

  • /// The creation of a new peri-urban district including functional and social mixing and a diversity of building typologies in an enhanced living environment. The largest passive housing operation in France. The largest passive housing opera- tion in France: the 318 passive Plus housing units are distributed among three programs:

    • The SOLEO – VILOGIA program: 110 flats in two buildings, as GF(ground floor)+3, allocated between housing for young workers, social housing, affordable housing and unrestricted housing.

    • TEMPO – BOUYGUES IMMO program: 140 flats distributed in 8 small buildings over 3 storeys. 15 to 20 flats will be unre- stricted housing.

    • PASSIVE’O – SAMO program: 68 rental flats for social housing only, distributed in 2 three-story buildings.

    /// Yosemite, first office building labeled Passivhaus Premium Built by the developer GSE and commercialized by Manac’h Immobilier, it is also the only office building in the region with a negative energy performance diagnosis (EPD) since it produces more energy than it consumes, largely from its roof equipped with photovoltaic panels. With a total surface area of 1,630 m2 divisible, as well as 56 parking places, it is stretches over 3 floors (GF+2).

    /// Management of costs and definition of a fair allocation of investments and management costs. Each stakeholder in the construction chain took its responsibilities to limit the construction and the housing management costs:

    • The planner: by defining critical operation sizes to ensure that the real estate operators benefit from the scale effect, • The urban planner: by defining plots limiting masking effects and optimizing free solar energy collection due to their orien-

    tation and a roof form predefined in the specifications for land transfer on the islet, • The real estate lessor and developer operators: by comparing a wide diversity of construction systems and technical equip-

    ment; by making use of arrangements of the design / realization type; by making their roofing available to solar investors without any fees,
